+# LTX 2.3 INT8 MSR
+
+## Summary
+
+Same-day `LTX 2.3` multiple-subject reference workflow from `javawock7618`. This is the more practical LTX drop if you care about mixing several references into one scene instead of just doing plain text-to-video.
+
+## Model Family
+
+- `ltx`
+
+## Status
+
+- `imported-only`
+
+## Source
+
+- Workflow pack page: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows>
+- Workflow file: <https://huggingface.co/javawock7618/comfy-ltx-2.3-workflows/resolve/main/LTX2.3_int8_MSR-javano2608.1.json?download=true>
+- Original publisher: `javawock7618`
+- Date imported: `2026-08-11`
+
+## Developer notes
+
+- The source README says this workflow can blend up to 5 inputs, including 1-4 subjects plus a background.
+- The pack is built around distilled GGUF and INT8 paths for `lightricks/ltx-2.3`.
+- The same pack also calls out an INT8 speedup path, prompt enhancement, and optional voice support in other graphs.
+
+## Our notes
+
+- This is one of the more interesting LTX variants for consistency and scene control.
+- On an RTX 3070 / 8 GB setup it is still tight, but it is a real workflow rather than a placeholder.
+- Good pick when you want a reference-heavy LTX path instead of a generic one-shot generator.
+
+## Required custom nodes
+
+- `ComfyUI-KJNodes`
+- `ComfyUI-LTXVideo`
+- the keyframe/director nodes named in the source README if ComfyUI flags them as missing
+
+## Required models
+
+- `lightricks/ltx-2.3` distilled GGUF or INT8 checkpoints
+- `ltx-2.3-spatial-upscaler-x2-1.1` for the detailer / upscaler lane
+
+## Notes
+
+- Best LTX import from this batch if you want reference blending and multi-subject handling.
+- Expect to trim resolution and keep the graph lean on an 8 GB card.
